A four-week trial found shifts in DNA methylation and immune patterns, but it did not show that participants aged more slowly.
Six of 15 adults tolerated more peanut months after treatment, but the experimental therapy did not eliminate their allergies or prove a lasting cure.
A yearlong trial found that medication and oral immunotherapy helped some children tolerate three allergenic foods, though most did not reach that goal and ongoing treatment was still required.
A new review examines how conventional breeding, genetic engineering and CRISPR could help improve the vitamin and mineral content of major crops as climate change places new pressure on food systems.
A large Japanese study found lower rates of some respiratory allergies but higher reported rates of food allergy among children exclusively breastfed for six months.
The findings do not show that the amounts commonly found in food harm the human gut.
An observational study found higher vitamin A levels were linked with better lung function in children and adults with asthma, while vitamin D showed similar links in adults.
A new study suggests some gut bacteria may get an advantage during weaning because they can use both breast milk sugars and fibers from solid foods.
A new study found that urolithin A, a compound made by some gut bacteria from foods such as pomegranates, walnuts and berries, activated pathways tied to intestinal barrier repair.
A new study found that trans-vaccenic acid affected immune development in mice, while human samples showed related links that need more research.
A new national analysis finds U.S. adults are using more supplements, with growing interest in products marketed for immune, gut, skin, joint and inflammation-related health.
An Australian study found egg allergy prevalence declined after infant feeding guidance changed, adding real-world support to recommendations that parents should not unnecessarily delay common allergens.
The study does not prove that one drink can reduce disease risk, but it offers a useful look at how researchers test functional food claims in people.
A new observational study in remote Amazonian Indigenous communities found that gut microbial diversity changed after medical visits, but the findings do not mean lifesaving treatment should be avoided.
A new review finds alcohol contributes to a wide range of diseases and injuries, but some risks may fall when people reduce or stop drinking.
A major genetics study suggests body weight can shape gut bacteria, but researchers say your microbiome alone does not determine whether you develop digestive disease.
A randomized trial found many peanut-allergic toddlers could tolerate more peanut exposure after carefully monitored oral immunotherapy, but experts stress this is not a treatment parents should try on their own.
A new lab study suggests cranberry juice compounds may help certain antibiotics work better against some UTI-causing bacteria, but researchers say human benefits remain unproven.
New research in humans and mice suggests eating may create a short-term metabolic state that can shape T cell readiness, though the findings do not mean specific meals or eating patterns directly “boost” immunity.
A new clinical study suggests an experimental treatment may help reduce some harmful effects of accidental gluten exposure, though it is not a cure.
A lab study suggests a non-heat treatment can change peanut proteins, but it’s far from making peanuts safe for people with allergies.
New research shows how compounds in breast milk support a delicate microbial balance, including bacteria often seen as harmful.
A small human study finds that while gluten can pass through saliva, the amount is typically low and easy to reduce.
Early lab research suggests certain high-fat diets could disrupt key protective cells in the gut within days, though the findings come primarily from animal models.
A new study finds that sleep patterns and diet both influence immune function, but through separate biological pathways tied to inflammation and long-term health.
